Founder · Igor Letinčić
FROM 300 PENALTY BURPEES TO THE WORLD CHAMPIONSHIP.
I finished my first OCR race in 2017. Since then, I have completed around 20 OCR events and more than 100 road, trail and ultramarathon races.
In 2017 I became Croatian national champion in the 100 km ultramarathon. I also competed twice in 24-hour ultramarathons, covering more than 200 km both times. In 2026 I completed the 55 km Spartan Ultra World Championship.
Beast Cave began after one race cost me more than 300 penalty burpees. I stopped looking for excuses and started building the strength, technique and endurance OCR demands. Now I use that experience to help others arrive prepared.
TEA
Theory of Evolutionary Adaptation
My own training model combines natural movement patterns, sport-specific work and intelligent load planning. My results were achieved with an average of under 20 minutes of daily training. There is no shortcut — every minute needs a purpose.
Beyond the obstacles
THE FOREST IS PART OF THE COURSE.
Forest trails, climbs and natural terrain are only minutes from the training ground — ideal for combining running and obstacle work.
Before you come
RAW MEANS RAW.
Beast Cave is an outdoor training ground, not a fitness centre. Come prepared for weather, dirt and uneven forest terrain.
